Description

holder

The invention relates to a holder with a fastening part and a receiving part, the fastening part and the receiving part being produced by reshaping a blank and the fastening part and / or the receiving part having at least one screw hole for inserting a clamping screw.

Holder as a connecting element of two or more components or as a fastening element for the use of various control units, sensors and. The like. Measuring devices are used in all fields of technology, in particular conveyor technology, installation technology, measuring and control technology and the like. Like., used in a wide variety of forms, with up to now mostly multi-part holder composed of castings are used. The known holders are therefore quite complex to manufacture, can only be adapted to their respective intended use to a limited extent and, because of their multipart nature, are also difficult to handle.

According to FR-PS 26 43 119, a clamp-like holder made of a correspondingly bent metal or plastic band is already known, the ends of the band being fixed to one another and to a component by means of a snap connection can be. Here, however, there are hardly any possible variations in the shape of the holder, and the joint fastening of the receiving part and the fastening part also necessitates that the object to be held be inserted into the holder simultaneously with the mounting of the holder on a component, which greatly limits the area of application of these holders. The same applies to a special fastening fitting for articulating a wire spring or the like described in GB-PS 11 62 521, which consists of a bent piece of perforated sheet metal and a plastic insert and by screwing the two sheet metal legs to the substructure at the same time is fastened with the clamping of the wire spring, so that there is in turn a direct connection between the mounting of the fitting on the substructure and the mounting of the object to be held in the fitting.

The invention is therefore based on the object of eliminating these deficiencies and of creating a holder of the type described at the outset, which can be produced rationally in a wide variety of forms and is distinguished by its skillful and varied applicability.

The invention achieves this object in that the fastening part and the receiving part are connected to one another via a web part and / or the screw hole or at least one of the screw holes as an angular hole arranged in the edge region of the blank, the corner edge of the hole breaks through, is formed. By using the stamping and bending process, the holder can be produced in a particularly simple manner from sheet metal or the like. Flat material with minimal effort, the web part connecting the receiving part and the fastening part opening up great design freedom for the holder and extensive adaptation of the Holder allowed to the respective holding conditions. The resulting holders are mostly in one piece, but in the case of complicated shapes they can also be welded together from a plurality of preformed sections and enable the receiving part and the fastening part to be handled individually, the fastening being carried out simply using clamping screws. Due to the special arrangement of angular screw holes in the edge area of the fastening or receiving part, clamping screws with edge attachments, such as door hinge screws or the like, can be used, which are secured against rotation when they are used, and on the other hand stand by the positioning of the screw holes close to the edge of the screw head and nut of the clamping screws used correspondingly far beyond the edge, as a result of which there is a sufficient clamping effect in the respective overlap area for the desired fastening. Thus, the clamping of the respective holder part to a supporting mounting plate or the like or with an object to be held can also be achieved with a screw, which nevertheless ensures the independent use and handling of the receiving part and the fastening part in the event of a short or completely missing connecting web . The holders are particularly suitable for use with machine parts, the wall thickness of which corresponds approximately to the sheet thickness of the holder, so that the holder fitted into a wall recess and the machine part can be clamped together perfectly, but other fastening screws can of course also be used with these screw holes use and any other fastening options can also be used.

By means of a corresponding design of the blank and the subsequent shaping, holders of a wide variety of spatial shapes can be produced, the design of the fastening part and the receiving part being practically unlimited. So the receiving part is mostly as a tongue or rag for forming a clamp for one Rod or pipe holder or as a flat plate for attaching flat workpieces or the like, but it is also possible to design special receiving parts, such as receiving hooks or eyelets, clamps or guide rails, etc., which are adapted to the most diverse purposes and devices to be accommodated. The same applies to the fastening part, from the simplest fastening plates to specially shaped fastening feet u. Any form freedom exists and it is of course also possible to exchange the function of the receiving part and the fastening part and, if appropriate, to use the fastening part as the receiving part and the receiving part as the fastening part.

A special holder shape results from the fact that the fastening part forms a fastening foot which lies within a circle determined by edge arches of the foot and / or edge breakthrough parts of screw holes in the fastening part, since such a holder is inserted into a bore of a machine part corresponding to this circle and can be tightened in any rotational position using the clamping screws. The foot sits within this hole in the machine part, the wall thickness of which corresponds approximately to the sheet metal thickness of the foot, and can already be fixed with a single clamping screw that overlaps the machine part and the foot with a screw head and nut or corresponding washers. The eccentric position of the clamping screw in relation to the foot and the bore also ensures that it cannot be rotated, so that a single clamping screw guarantees excellent support conditions for the holder.

If the fastening foot has a radially projecting fixing lug, for which fixing lug a corresponding recess or bore is provided in the machine part receiving the holder, it is also possible in this way with only one clamping screw reach a precisely non-rotatable bracket.

It is also advantageous if, in the case of a fastening part, the edge profile of which has at least one pair of mutually opposite, parallel straight sections, the screw holes are provided in the region of the straight sections. Such a fastening part permits the use of a holder in guide rails or grooves, the straight sections being adapted to the groove width and the fastening part therefore being able to be clamped to the edge of the groove by means of the clamping screws, the straight sections then guaranteeing a rotationally secure support. If several straight sections offset from one another are provided, the holder can in turn be fastened in different rotational positions.

If the receiving part and the fastening part form rectangular plates connected to one another via the web part, the web part and the fastening part preferably being inclined relative to the receiving part, a side view of a U-shaped holder with superposed fastening and receiving parts can be produced, which holder is used, for example in guide rails or grooves, the fastening part engaging in the groove acting as a sliding block engaging behind the groove. Through an inclination of the fastening and receiving part, after the insertion of the fastening part into the groove and its twisting engagement for the actual fastening, the remaining receiving part is aligned in parallel to the guide rail by this twisting, which ensures a proper adaptation of the objects to be assembled. For the actual fastening, at least one screw hole is provided in the fastening part, so that the fastening part rotated behind the groove in the groove can be clamped to the groove edges by the clamping screw used here. Another favorable embodiment results from the fact that the fastening part forms two parallel tabs with laterally projecting attachment lugs, the tabs being bent apart in opposite directions and the lugs being angled in a U-shape, which lugs have parallel bevels on the facing corner areas. Such a holder or the like can be placed on the flange of an I- or T-beam. be attached by attaching the fastening part transverse to the bevels of the fastening lugs on this flange and then rotating it into its normal position, so that the fastening lugs overlap the flange and the holder can be clamped to the flange. It goes without saying that any mounting part can be combined with such a mounting part, which basically applies to all forms of mounting and mounting parts of the holder according to the invention.

Another way of a special adaptation of the holder to the respectively existing operating conditions results from the fact that fastening part and the receiving part with an arcuate, 90 ^* rotatable web portion ver¬ connected are thereby fixing part and the receiving part can be mutually shifted by 90 ^* angularly offset or a Umgrei ¬ opening of an object to be held. Such a holder is suitable, for example, for the hanging fastening of transport rails or the like, the fastening part being fastened to a carrier and the receiving part engaging under the transport rail and supporting it from below. Different fastening and receiving part shapes can also be selected here, the receiving part, for example, sliding block-like approaches for engaging in a guide groove or the like. can have.

The receiving part forms one between a straight section of the edge course and a longitudinal slot parallel to it Receiving web, which is bent out by cranking at the end into a parallel plane at a distance from the plane of the other receiving part and has a screw hole along the edge of the slot and / or the straight section, components can be plugged onto this web with a fastening slot adapted to the receiving web and thereby shaped - and non-positively mounted on the holder. If the fastening slot is longer than the bent-out web area, the component can be adjusted for sliding and thus adjusted during assembly.

It is expedient if the receiving web is inclined with respect to the vertical mounting direction, the slot edge and / or the straight section preferably having a free middle section, since a height adjustment of the mounting position is also achieved by a sliding adjustment.

In the drawing, the subject matter of the invention is illustrated schematically in several exemplary embodiments, namely that FIG. 1 shows a blank of a holder according to the invention in FIG

17 and 18 another embodiment of a holder according to the invention as a cut in plan view and in finished form in the diagram and

19 and 20 a further exemplary embodiment of a holder according to the invention using a receiving part as a blank and in finished form in plan view or in the diagram.

In order to produce holders rationally and to be able to adapt their shape well to the respective application, these holders are manufactured by reshaping a one-piece stamped part, the shape of which corresponds to the network of the basic geometric holder shape, which stamped part is then bent to the respective holder.

According to the embodiment of FIGS. 1-3, a holder 1 for fastening a rod S or the like. provided on the wall W of a machine part, not shown, for which purpose this holder has a fastening part 2 and a receiving part 4 connected to this fastening part 2 via a web part 3. Clamping screws 5 with square shoulder 6 serve on the one hand for fastening the fastening part 2 on the wall W and on the other hand for tightening the clamp formed by the receiving part 4 and enclosing the rod S. To produce this holder 1, there is a blank 1a with a rectangular tab 4a for shaping the receiving part 4 and one via a connecting piece 3a as a web part

3 attached foot 2a as a fastening part 2. The connecting web is angled relative to foot 2a and the remaining blank la is bent together with tab 4a to form the mounting bracket, square square holes ^{~ being provided} for the use of the clamping screws provided for the bracket. In the foot 2a there is a square hole 8 as a screw hole, which is located in the edge region 9 and with one of its corners 10 breaks through the edge course 9, so that this hole can be punched like the others without difficulty. Of course, the foot 2a can also have further screw holes 8, as indicated by dash-dotted lines, and it is also possible to equip the foot 2a with a fixing lug 11. The edge 9 of the foot 2a runs in a circular arc and thus defines a circumferential circle K within which the entire foot 2a is located.

2, the holder 1 is now inserted into a wall bore B, the diameter of which corresponds to the circumferential circle K of the foot 2a, so that the fastening part 2 of the holder 1 is rotatably seated in the bore B. For fixation, a clamping screw 5 with nut and washer is inserted into the screw hole 8, the screw head 5 and the washer 5b overlapping both the foot 2a and the wall area W adjacent to the bore B and thus the holder in the wall Clamp W. The eccentric position of the screw 5 at the same time results in an anti-rotation lock, loosening the clamping screw ^~ making simple rotation adjustment possible without risk of the holder falling out of the bore B and tightening the clamping screw 5 giving the desired positioning. According to the assembly example according to FIG. 3, the holder 1 with its fastening part 2 is placed on the wall W of the machine part and the clamping screw 5 is simply pushed through a corresponding wall hole B, so that a conventional clamping screw connection takes place. Here, an additional bore Z for the engagement of the fixing lug 11 is arranged to prevent rotation.

The holder 101 according to FIGS. 4 and 5 with its fastening part 102 and its receiving part 104 consists of a blank 101a, which in turn comprises a tab 104a for shaping the receiving part 4 and a foot part 102a for forming the fastening part 102. Here, the foot part 102a forms an edge 109 which has two pairs of mutually opposite, parallel straight sections 109a, 109b, so that the holder 101, which has a clamp which serves as a receiving part 104 and is bent up relative to the flat fastening part 102, with the associated straight sections 109a, b between the edges of a guide groove N or the like. can be used where fixation takes place via corresponding clamping screws 5 with the screw heads or washers overlapping the groove edge regions. The straight sections prevent rotation of the holder within the groove, the two pairs of straight sections permitting positions within the groove N which are offset in relation to one another. Here, too, the screw holes 8 are designed as square holes with corners 10 breaking through the edge 109.

A similar holder 201 is shown in FIGS. 6 and 7, which holder consists of a blank 201a, the foot 202a of which forms an edge 209 with a plurality of pairs of straight sections 209a-d offset from one another. A tab 204a extending through incisions into the foot 202a can in turn be bent up to a clamp as the receiving part 204 of the holder 201, so that this holder 201 with its cover Fixing part 202 can be adjustably fixed in a corresponding groove N in a plurality of angular steps corresponding to the number of pairs of straight sections.

The holder 301 according to FIGS. 8 and 9 likewise has a fastening part 302 which can be inserted into a groove N and a claw-like receiving part 304 for holding an angled rod S. The blank 301a of this holder, which can only be mounted at an angle of 180 ^* , has an approximately rectangular foot 302 with opposite straight sections 309a of the edge 309 with the corresponding screw holes 8 and three adjacent tongues 304a for molding of the receiving part 304.

According to the exemplary embodiment according to FIGS. 10 and 11, a holder 401 is illustrated, the receiving part 404 and the fastening part 402 of which are connected to one another via a web part 403 and are angled toward one another approximately in a U-shape. The blank 401a is therefore composed of two rectangular plates 404a, 402a and a connecting web 403a, the connecting web 403 and rectangular plate 402a being inclined relative to the rectangular plate 404a, so that the fastening part 402 of the holder 401 can be inserted into a correspondingly wide groove and then, by rotating the receiving plate 404 in the longitudinal direction of the groove, the holder is inserted into the undercut groove so that this holder 401 or the like acts as a sliding block for fastening various objects along a guide groove. can serve.

A similar sliding block is illustrated in the exemplary embodiment according to FIGS. 12 and 13, wherein the holder 501 shown here only with its fastening part can be inserted in an arcuate groove N and fixed using a clamping screw 5. For this purpose, the blank 501a has a plate part 502a with correspondingly arc-shaped edge sections 509a, so that a fastening part 502, which is adapted to the groove shape and is guided along the groove and is displaceable, is produced. Here, a correspondingly angular screw hole 8 is arranged in the area of the edge 509 in order to allow an overlapping clamping with the clamping screw 5. Any receiving part can be formed on the web part 503, which is only indicated, for which purpose the cut 501a should have a shoulder adjoining the connecting web 503a.

According to the exemplary embodiment according to FIGS. 14-16, the holder 601 has a fastening part 602 with which it is attached to an I-beam T or the like. can be applied. Various holding parts shaped in accordance with the intended use can in turn be connected via the web part 603. The associated blank 6θla forms two parallel tabs 602a, which have laterally protruding attachment lugs 602b. To produce the holder 601, these tabs 602a are bent apart in opposite directions and then the lugs 602b are angled in a U-shape with respect to one another, bevels 602c being provided on the lugs. These angled lugs result in hooks encompassing the flange of the carrier T laterally, the bevels 602c, when the holder 601 is rotated accordingly, allowing the fastening part 602 to be placed on the flange and then turning back provides a position which overlaps the flange. Angular screw holes 8 then enable a suitable clamping of the fastening part 602 on the carrier T.

The holder 701 according to FIGS. 17 and 18 has a clamp-shaped fastening part 702, an arch-shaped web part 703 and a sliding block-like receiving part 704, so that with this holder 701 transport rails or the like. can be hung. The associated blank 701a forms a rectangular end tab 702a as a fastening part and sliding block lugs 704a formed over an edge web as the receiving part, an arcuate connecting web 703a connecting the two end regions to one another. A corresponding bending of the end tab 702a creates the fastening clamp 702, twisting of the connecting web 703 by 90 ^* results in the web part 703 and multiple bending of the sliding block extension 704 leads to the receiving part 104 which can be inserted as a sliding block in an undercut groove.

As can be seen in the exemplary embodiment according to FIGS. 19 and 20, the holder 801 can have a receiving part 804 which forms a receiving web 12 between a straight section 809a of its edge 809 and a longitudinal slot 15 parallel thereto. This receiving web 12 is bent over end crankings 13 parallel to itself from the receiving part plane, so that a connecting plate P or the like. with a corresponding fastening slot SZ, it can be slid on the receiving web 12 and can be fixed in the desired position with a clamping screw 5. The associated blank 801a therefore only needs to be produced with a corresponding edge profile 809 and a longitudinal slot 15, the slot edge 14 delimiting the receiving web 12 forming an exposed central section 14a and the straight section 809a having a screw hole 8. The holder 801 thus allows a full support of the connecting plate P and a sufficient clamping fixation, the side and height adjustment being possible due to the inclined course of the receiving web 12. The receiving part 804 can in turn be molded onto the various fastening parts via its web part 803, a combination with the fastening part 601 according to FIGS. 14-16 being appropriate.
